django-virtualenv-wsgi

Django WSGI handler setting up a proper environment based on Virtualenv, with possible server maintenance message (503 Service Unavailable) responding.

Usage

Default project tree should look like:

some_project
|- _env/
|- django_project/
|- django.wsgi
|- maintenance.html
|- maintenance.lock

• _env/ virtualenv environment directory
• django_project/ django project package directory
• django.wsgi a django.wsgi file from this package
• maintenance.html a HTML file (UTF-8 encoded) with which server will respond in maintenance mode
• maintenance.lock maintenance mode lock -- see below

You must make sure that your Django project directory name is same as in a django.wsgi's PROJECT_NAME setting.

Maintenance mode

To enable maintenance mode just create a maintenance.lock file in the same directory django.wsgi is located, and tell your server to reload the WSGI handler. You can do all of this with a simple line:

$ touch maintenance.lock ; touch django.wsgi

To disable maintenance mode just remove maintenance.lock and reload the handler:

$ rm maintenance.lock ; touch django.wsgi

In case maintenance.html doesn't exist server will respond with default plain text message (you can change it with django.wsgi's MAINTENANCE_MESSAGE_FALLBACK setting).
